DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 372,655, dated November 8, 1887.

Application filed February l, 1887. Serial No. 226,151. (No model.)

To @ZZ whom z5 may concern:

Beit known that I, CHanLns M. CAsHIN, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvementin Burglar-Proof Door-Checks, of which the following description, in connection with the accompanying drawings, is a specification, like lett-ers on the drawings representing like parts.

This invention has for its object to provide a burglar-proof door-check which is especially adapted to be used by com mereial men or drums mers on the road.

My improved door-check is small in size and weight, and can be easily carried about the person from place to place without inconvenience. lt is especially adapted for use in hotels and lodginghouses inthe summer-time, when it is desired to effect a circulation of air through a bed-room.

By means of my improved door-check the door of the room may be opened to any desired width, which in most cases will be sufticient to admit a considerable quantity of air, and yet not large enough to admit the body of a burglar.

The particular' features in which my invention consists will be pointed out in the claim at the end of this specification.

Figure lis a side elevation of my improved hurglarproof door-check; Fig. 2, a section of Fig. l on line x x, and Fig. 3 a section of Fig. l on line x x with the pad omitted.

The base or body portion a will, for the best results, be of metal, cast to leave a beveled or inclined upper face, a, and an oppositely-i11 elined rear face, a, the latter face having teeth or prongs b projecting beyond the bottom line of the body a.

rlhe base or body portion a is cast so as tov leave a hollow or depression in the inclined upper face, ct, having a bottom, b2, substantially parallel to the said upper face, the opposite ends of the said hollow or depression having, as herein shown, an opening, b3, for a purpose to be described.

The hollow or depression in the inclined npper face receives within it a pad, c, preferably of rubber, which for the best results is molded, it having at each end a tongue, e', adapted to be inserted through the opening b in the ends of the said hollow depression, to more securely keep the rubber pad in place. The rubber pad c will also preferably be beveled, as shown.

ln the application of my improved doorcheck it will be placed upon the iloor away from the door the distance it is desired to open the latter, the bottom of the door passing` up the inclined face, when the door is opened, until it comes in contact with the rubber pad. If the door is pressed upon from the outside to open it still wider, the pressure exerted upon the said door will force the teeth or prongs into the floor, thereby offering a resistance to the pressure upon the door. The greater the pressure upon the door the firmer the teeth b are driven into the iloor, and consequently greater resistance is offered to the opening of the door.

My improved door-check may also be kept permanently in the room, and, if desired, it may be fastened by a chain (not shown) to the wall near the door.

It will thus be seen that the door may be left ajar to admit air into the room, which is especially advantageous in summertime Without any danger or fear of being burglarized.

A burglar-proof doorcheck comprising the one-piece cast-1netal base or body portion a, having the inclined face a', provided with a hollow or depression, and the oppositely-inclined face a2, having teeth b, combined with an elastic pad fitted into the hollow or depression in the face c, as and for the purpose specified.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.

CHARLES M. CASHIN.
